to the cy inders o the gas engine.

Another object ofthe invention lies in providing an improved charge heatingfdevice in which ahigh degree of radiation of the heat will take place to the end that the `entire mass of the charge passing through the pipe may be heated adequately and uniformly whereby to #promote ready Vaporization in the combustion chambers ofthe engine and complete combustion without the formation of carbon deposits.

A furtherobject of the invention is to provide an improved heater constructed simply and inexpensively and. so arranged and disposed as to permit of its instalihtion upon the fuel charge ipe without entailing any modification or a teration therein.

With the foregoing and` other objects in view, the invention will be more fully de9 scribed hereinafter and will be more particularly pointed out in the claims appended hereto.

Referrin more particularly to the, drawings, 6 in icates the pipe which extends between the carbureter and the internal combustion engine or intake manifold. and in this pipe 6, as shown in Figure 4, the improved heater is Hla'ced by installing it throu h a' side wa of the pipe perforated for t e ,purpose of receivin the flanged linsulating sleeve 7 through w ich is mounted the ltubular externally threaded varm 8. This arm 8 contains the rcelain or other insulating sleeve 9 throng -which passes one of the leeds 10. thereon the nuts 11 and 12 for holdingsaid resent invention relates to improvelike syxnbols re-A lan View, with arts The arm 8 has threaded4 arm in place. The nut 11 is run up against the flange 7 of the insulating sleeve and this flange is forced tightly against the linner wall of the pipe 6. The outer nut 12 is screwed up tightl against the insulating washer 13 which of the pipe 6. A binding nut 14 is also threade upon the arm 8 and cooperates with the nut 12 to hold the otherlead 15 therebetween. A battery or other source of current is indicated at 16,1as included in the circuit and 15, together with the switch and vfuse block 17 having different ampere fuses whereby to regulate the degree of the heat of the device.

The tubular arm 8 is provided with a liat extension 18 extending approximately mto the center of the pipe 6 where it receives and lsupports the base 19 of a receptacle for 4'vid'ed'with the radiating fins 24 which increase in width from the lower to the upper portion of the receptacle and arev tapered or inclined at their 'outer edges to agree sub. stantially with the conical taper of the side wall 21.

The lextension 18 of the arm and the baseortion 19 of the receptacle are both perorated to receive the insulating sleeve 25, thel lower end of which engages and rests 'upon the 4insulating washer 26 fitted beneath the extension 18 and held thereto by the nuts 27 and 28 threadedupon the stem 29, which `passes up through' the insulating sleeve 25 and into the lower portion ofthe receptacle where such stem sprovided with the conical `head 30. The nuts 27 and 28 are adaprteld to receive the lead 10 therebetween. `e insulating sleeve extends up within the receptacle-above the base'19 thereof, and, at the up -r yend of 'the insulating sleeve 25 is are atively large wide spread ilange 31. This flan e is spaced belowthe base of the cone hea 30 andit extends tilllipost thev lfull diameter of the receptacle at point. The carbon particles 20 may be packed into the ts against the outer wall hase of the receptacle'about the insulating sleeve 25 and beneath the flange 31.

The receptacle is constructed from a blank such as shown in Figure 5. In this blank the dotted sinall circle 32 indicatesthe line bounding the outer edge of the base 19, upon which line the'sidc wall 2l is bent up. The various ins are made by folding certain portions of the side wall upon itself. The lines ot' llexui'e are three in number each fin comprising a-central line 33 which is a true radius and which represents the outermost portion of the lin. rllhe other dotted lilies :tt and 35 at cach `side of the radial line 33 are made at an angle to the radius of the blank or receptacle and they join with the radial central line 33 at the point 36 which is the lowerniost part of the tin.

In the use of the device the circuit is conipleted by throwing the switch-3T, indicated in Figure 4, so as to direct inoreor less cui'- rcnt through the device. This current passes from the battery i6 through the .switch box into lead l() which passes through the sleeve insulator 9 and to the binding nuts 2T and 29, to the stein .29 and upwardly tov the cone head 30 thereof, which lies enibcdded in the mass of carbon particles in thei receptacle. The current is distributed `to the carbon particles over wide area by this conical head and after passing through the carbon particles, the current will gain the wall 21 of the receptacle and return through the arm 8 and its extension 18 and Wire 15 back to the battery 1G. The passage of the current through the minute carbon particles will generate heat and this heat will be rapidly picked up and given off b'y the metal receptacle and its tins. In fact the tins possessing substantially the double Walls' 38 and 39 at opposite sides of the central line 33 on which the -fins are folded, will provide a relative great Y surface against which the charge may strike and also a relatively great radiating surface for the escape of the heat from the metal. Preferably a Vmetal having a high conductivity will be selected for the receptacle.

Due to the conical arrangement of the side wall 21 'of the receptacle and the upwardly progressive Width of the fins, the

rising charge in the pipe 6 will be forcibly brought into contact with such receptacle side wall or the side walls 38 and '39 of-its fins. An enforcedheating of the charge will result. Consequently when the char arrives in the combustion chambers of t e engine it will be completely vaporized and will be ina condition for v,ready and complete combustion, so that a quick starting of the motor may be had and the fouling of the plugs in the combustion chambers avoided.

It is obvious that various changes and niodications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereol, such changes and modifications being restricted only by the scope of the following claims.

What is claimed iszl. A vaporizer for internal combustion engines comprising a receptacle having a inass ot' resistance particles therein and provided with external this, means to hold said receptacle in the engine intake pipe, and a circuit including said particles and receptacle.

2.- A vaporizer for gas engines comprising a inverted rusto-conical receptaclehaving tins, a -inass of resistance particles therein, means to hold said receptacle in the engine intake pipe, and a circuit including said receptacle and particles 3. A vaporizcr for internal combustion engines comprising an inverted Substantially tiustoconical receptacle for carbon particles having lins bent from the wall thereof, said tins having double walls and inclined outer edges, means for supporting said receptacle in the intake pipe ot the engine, and a circuit including said particles and receptacle.
